The electric force between A and B will increase.
Explanation:
It takes the car 14 seconds to stop
Explanation:
A car is traveling at a constant velocity of 19 m/s when the driver puts
on the brakes to accelerate it at -1.4 m/s² until stopped
1. The initial velocity is 19 m/s
2. The acceleration is -1.4 m/s²
3. The final velocity is zero
We need to find how long it takes the car to stop
We can find the time by using the rule
→ v = u + a t
where v is the final velocity, u is the initial velocity, a is the
acceleration and t is the time
→ v = 0 m/s , u = 19 m/s , a = -1.4 m/s²
Substitute these values in the rule
→ 0 = 19 + (-1.4) t
→ 0 = 19 - 1.4 t
Add 1.4 t to both sides
→ 1.4 t = 19
Divide both sides by 1.4
→ t = 13.57 ≅ 14 seconds
It takes the car 14 seconds to stop

A star's apparent brightness is the brightness seen by humans on Earth. A star's absolute brightness is its actual brightness and does not depend on where the star is viewed from.
